WHY?
PHYSICS and GEOMETRY never lies.....
THIS ARMWAND IS OPTIMIZED FOR
LOWEST TRACKING DISTORSION
3 THINGS DETERMINE THE QUALITY AND THE PERFORMANCE OF A PERFECT TONEARM:
1) EFFEKTIVE LENGHT
2) OVERHANG
3) OFFSET ANGLE
============================
TONEARM GEOMETRY:
EFFEKTIVE LENGTH : 321.459 mm
MOUNTING DISTANCE: 309.4mm
OVERHANG: 12.66 mm
OFFSET ANGLE (DEGREES): 16.9 º

==========================
ORTOFON 12" AS-309 TONEARM HAVE LESS DISTORSIONS AS THE SME 3012 series I
ORTOFON AS-309 12" long compared to SME 3012 series I
309.4 mm mounting distance 294 mm
321.5 mm effektive lenght 305 mm
12.6 mm Over hang 11 mm
16.9 º offset angle(degrees) 16.15 º
1.26 º maximum error º 2.11 º

Tonearm geometry with the lowest distortion worldwide, you will hear it immediately
the geometry had to be calculated by hand in the 60s, because you did not have any computer calculation programs yet, this could never be the optimum, because the 3 parameters for the geometry are interdependent. When you change only one parameter to 0.5mm the distortions are great. Therefore, tonearms from the 60s can NEVER reach the perfection that is possible with the computer programs today
___________________________________
This tonearm combines the simple aesthetics of Ortofon Tonearms with the current best armtube geometry currently available
only a perfect geometry of the armtube guarantees a low distortion.this is the first and most important thing with a tonearm.not the material, not exotic armtube materials or mimics can eliminate a fundamental distortion that exist due to a wrong and bad geometry.material of the armtube and Vaccination only has an impact on resonance and vibration coming from the plinth (engine vibration and music waves) tonal arms are offered on the market, which cost well over $ 15,000 and are advertised that give the materials the highest in technology (space travel, NASA ect)
the geometry of a perfect tonearm with the lowest distorsions consists of:
1) effective length
2) overhang
3) offset angle
nothing more and nothing less
these 3 parameters are dependent on each other. This is mathematics and is based on formulas that have absolutely nothing to do with materials. With existing PC calculation programs, anyone can see if their tonearm has the least distortion due to the armtube geometry. This is the only objective method and not the subjective belief in exotic materials or great promises..

here 2 of many
Aligned. It is in an aftermarket VTA tower made for the Groovmaster IIti that was on the table before your arm.
I will not going back to the GM!!! Only my $11,000 Glanz MH124 is superior and
not by $10,000!
I am thrilled at this arms performance richness of tone is it's major strong point.
Bass is tight super extended and the too end extended and sweet.
No ringing or tonal artifacts with this arm.
Vocals are on par with the best of the best. Rich defined and harmonical.
Thank you sir. Well done!

My Ortofon tonearms go over the SME 3012 and SME 3012R, which costs about 5000 euros. It is only surpassed by a GLANZ for $11,000. That's not what I'm saying, but my customers.
see here original mails
Dear mr. BokrandI gave myself some time to make sure I wasn’t too hasty in judging. After many hours of listening to my favorite records, which I know very well, I can say that your arm holds up very well the comparison with my beloved SME 3012R, indeed, with the Ortofon SPU is superior in clarity, dynamics (!!!), soundness of bass...
Thanks for everything
